Retinal Imaging and Optical Coherence Tomography of Choroidal Haemangioma Mimicking Central Serous Chorioretinopathy

Intraocular tumours, such as choroidal haemangioma, can cause exudative retinal detachments, which mimic central serous chorioretinopathy. Key symptoms of a choroidal haemangioma include reduced visual acuity, visual field defects, and metamorphopsia. More rarely, it can cause photopsia, myodesopsia, and pain. Important differentials include choroidal melanoma and metastases, for which an ocular oncologist should be consulted. Prompt treatment is required for the regression of tumour and to prevent choroidal atrophy and permanent visual loss. Here, we report the case of a 44-year-old lady who was found to have a choroidal haemangioma with macular subretinal fluid, highlighting the differentiating features from other intraocular masses.
